Body onload function in content page in asp.net:



In this post we will discuss how to use body onload function in content pages in asp.net.

Also you can check out my previous posts on:

There are two approaches we can write body onload function in content pages.

1st approach:
<script type="text/javascript">
        document.body.onload = function () {alert('I am OK'); }
</script>

2nd Approach:
Modify the body tag by adding runat = "server" attribute like below:

<body id="body" runat="server">

Then in the content page in Page_Load write like below:

 protected void Page_Load(object sender, EventArgs e)
    {
        HtmlGenericControl body = (HtmlGenericControl)Master.FindControl("body");
        body.Attributes.Add("onLoad", "alert('I am also OK');");
}

Hope it will be helpful to you!
